I have compiled system image building and now when I open the DLL I get warrning.  
`WARNING: using Base.e in module Main conflicts with an existing identifier`  
I think it’s something in my userimg.jl.  
What can it do?  
Thanks.

This causes this piece of code with assignment `e=5` in my userimg.jl.  
`@enum MY_ImportanceType a = 1 b = 2 c = 3 d = 4 e = 5`  
Why and how to solve such a problem?  
I know that e = 2.7182818284590…
